Andreas Lubitz, the co-pilot who was flying the Germanwings Airbus A320 jetliner that slammed into a mountain in the French Alps on Tuesday, sought treatment for vision problems that may have jeopardized his ability to continue working as a pilot, according to new reports. had previously reported that Lubitz had been dumped by his girlfriend the day prior to the crash and was undergoing treatment for depression, for which he was on multiple psychiatric medications.

Heather Childers reported on "America's News Headquarters" that Lubitz may have visited an area near the crash site as a child. A member of the German Gliding Club said that between 1996 and 2003 Lubitz's family were regulars at an airfield in the town of Sisteron, about 30 miles from where the plane went down.

Amy Kellogg reported that, "An ex-girlfriend who was a flight attendant told Bild newspaper that Lubitz had once warned one day he would carry out an odious act the world would remember him for, that he would change the system."

Kellogg said that that ex-girlfriend also revealed that Lubitz had been buckling under work pressures, was volatile at times and would sometimes wake up in the middle of the night screaming, "We are going down!"

Kellogg added that a top French investigator is trying to back off the widely accepted scenario that Lubitz intentionally crashed the plane because of mental issues. Although French investigators are still going with that theory, they need to keep other options, such as a mechanical issue, open.

According to Kellogg, the French Pilots Union has filed a lawsuit because of the leaks in the investigation. They also have their own doubts about what was captured on the aircraft's voice recorder, because the Airbus A320 has such a notoriously noisy cockpit that it would have been hard to hear the breathing that led investigators to believe that Lubitz was alive and conscious at the moment of the crash.
